Specification of Letters Patent.

Patented Mar. 9, 1920.

Application filed March? 10, 1919. Serial No. 281,666.

To all whom it may concern.

Be it knownthat' I, ADOLPI-I P. Rrrrnn, a citizen of the United States,and a resident of the city of Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements-inSpokeshaves; and I do hereby declare that, the following is a full,clear, and exact description of the same, reference being bad to thedrawings and to the numerals of reference marked thereon, which form apart of this specification.

This invention relates to an improved type of spokeshave or wood shavingtool, whereon a gage is adjustably mounted and releasably locked'in anadjusted position to permit the spoke-shave to be operated to out agroove of a predetermined width in a pieceof wood.

It is an object of this invention to provide a spoke-shave with anadjustable groove galg'e.

It is also an object of the invention to construct a: spoke-shaver topermit a gage to be slidably mounted thereon. to facilitate the cuttingof grooves ofuniform, width.

Another object offthe inventionds the construction of a wood shavingtool wherein an adjustable gage mounted on the groove body of the toolis adapted to be held in an adjusted position by means of retainingscrews which are positioned to engage in the body grooves.

A further object of this invention is the construction of a spoke-shavewherein the margins of the knife slot are provided with scale markingsto permit a gage on said spoke-shave to be set in an adjusted positionwhereby a groove of uniform width can easily be cut by the spoke-shave.

It is furthermore an object of the invention to provide a spoke-shavewith an adjustable gage adapted to be set by means of a divided scale sothat a groove of uniform Width may be conveniently cut in a piece ofwood by the spoke-shave blade.

It is an important object of this invention toprovide a right and lefthanded spokeshave of simple construction adapted'to be used with orwithout an adjustable gage.

Other and further important objects of the invention will be apparentfrom the dis closures in the drawings and specification.

The invention (in a preferred form) is illustrated in the drawings andhereinafter more fully described.

On the drawings Figure 1 is a bottom plan view of a spokeshave embodyingthe principles of this invention.

l1 ig. 2 is a rear side elevation thereof showing the same set forcutting a groove of a predetermined width in a block of wood.

Fig. 3 is an enlarged detail section taken on line 3-3 of Fig. 2, withparts in elevation.

Fig. i is an enlarged bottom plan view of the spoke-shave with thehandles broken off" and with the gage removed to show the scalemarkings.

As shown on the drawings The spoke-shave is made of metal and comprisesa body' portion or'stock l, having handles 2 secured on opposite endsthereof. The handles may be adjustable if preferred. The bottom surface3, of the stock 1, is smooth and slightly converted and is provided witha longitudinalslot 4. Each of. the longitudinal 'margins bordering theslot at, is] provided with a divided scale 5, as clearly shown in- -Fig.4. Formed in the stock 1, is an inclinedsurface; 6, having a threadedaperture formed therein. Resting upon the inclined surface 6, is a knifeor blade 7 provided with an opening 8, and having the cutting edgepositioned to project through the slot 4. A retaining plate 9, isremovably placed above the blade 7 and is provided with an integralpassaged boss or collar 10. To removablv hold the blade 7 and the plate9, in position, a screw bolt 11, is engaged-through'the passage collar10, and through the blade opening 8 and is removably threaded into thethreaded opening provided for the purpose in the stock 1. The head ofthe retaining screw bolt 11. is knurled to permit easy operation of saidbolt. The slot 8, permits the blade 7 to be adjusted when the bolt 11,is loosened.

Cut or formed in each of thelongitudinal sides of the stock 1, is aguide groove 12, which extends the whole length of the stock and is openat both ends. A channel shaped metal gage 13, is provided, having theends 14 thereof, bent at an angle and provided with integral guide teethor tapered projections 15, on the inner surfaces thereof to slidablyengage in the stock grooves 12, as shown in Fig. 3. The gage is curvedcomplementally with the convex surface 3, of

the stock. Each ofthe gage ends 14, is pro vided with a threaded passagt m the purpose of holding the gage locked knurled head set screw 16, tobe' removably or adjustably threaded therethrough to perg mit the innerend of the screw to lo'ckingly engage in one of the stock grooves 12,for

against movementin an adjusted position. As shown in Figs. 2and 3, thespoke-shave is positioned to cuta groove or rabbet in a wooden'block 17A notch or recess 18, is provided in the inner surface of the gage 13,to permit the gage to clear the cutting edge of "the blade 7.

The operation is as :t'ollows:-

. Thespoke-shave may be made of steel or As shown in Fig. 1, the gageset at fivev eighths ofan inch. The gage is held locked against movementin an adjusted position on the stock 1, by simply tightening the setscrews 16, which trictionally engage on the stock grooves 12.

To cut a groove of a selected width in the block of wood 17 thespoke-shave is placed as shown in Fig. 2, with one side of the gageabutting the side of the block to act asa guide for thespoke-shave;Thespokeshave is operated by means of the handles 2, and the cuttingedge of the blade 7, will cut agroove'of uniform width in the'block 9.Thezspoke-shave may be used as either a left handed or right handedtool, and the gage may be set with respectto either ends of the scales5'; The spoke-shave maybe' used on eitherstraight or curved pieces ofwood. When desired, the "gage may be completely removedfrom the stock 1,and the spoke shave used without the gage.

I am aware that many changes may be made, and numerous details ofconstruction varled through wide range wlthoutde parting from theprinciples 'of'this inven tion, and. I 'th'ere foi'e do notpul'poselimit ing the patent granted otherwise than neces sitated by theprior art.

I claim as my invention The combination with a spoke-shavehave mgsimilar guide grooves in the sides there of, of a gage, means integrallyformed on said'gage adapted to slidably engage in said' guide groovesand thus maintain the gage in slidable contact withthespoke 'shave,

and set screws projecting through said means and adapted to engage 111said grooves to hold saldgage lockedagainst movement in anadjustedposition on said spoke-shave.

In testimony whereof I have hereunto subscribed my name in the presenceof two subscriblng. witnesses.
